buildapp loads and compiles w/Clozure Common Lisp

  A number of new interoperability functions and macros in utils.lisp
  which are used in dumper.lisp and in buildapp.lisp.  A `ccl' field
  added to the `dumper' class.  And some #+sbcl and #+ccl conditional
  forms in buildapp.lisp to correctly compile executables with ccl.
build buildapp with Clozure with 'make LISP=ccl'
documentation reflects the addition of CCL support
